Review request for hive.
Summary
-------
UNION ALL on columns of different types is semantically allowed but throws a
runtime exception due to bugs in getting the correct object inspector after the
parent MR input file is change and in setting the TypeInfo for the union row
schema.
This addresses bug hive-2305.
https://issues.apache.org/jira/browse/hive-2305
